Nighttime Sleep Regression -- HELP!

Switzerland

DD is almost 8 weeks old. She was doing great from week 4/5 thru 6 about sleeping somewhat consistently at night -- sleeping the first block in 4 hrs then up every 2/3 hrs to feed..... but now the last two weeks it's been chaos. I am up every 2 hrs to feed her and she doesn't seem to even want to shut her eyes till almost midnight! (Used to be around 9 pm)

 I am exhausted....any suggestions? Will it get better? Should I be doing something differently now?

 Thanks!
